Iranian scientists have run computer simulations for a nuclear weapon that would produce more than triple the explosive force of the World War II bomb that destroyed Hiroshima. …

The International Atomic Energy Agency – the Vienna-based U.N. nuclear watchdog – reported last year that it had obtained diagrams indicating that Iran was calculating the “nuclear explosive yield” of potential weapons. …

The IAEA report mentioning the diagrams last year did not give details of what they showed. But the diagram seen by the AP shows a bell curve – with variables of time in micro-seconds, and power and energy both in kilotons – the traditional measurement of the energy output, and hence the destructive power of nuclear weapons.

The curve peaks at just above 50 kilotons at around 2 microseconds, reflecting the full force of the weapon being modeled.

The bomb that the United States dropped on Hiroshima in Japan during World War II, in comparison, had a force of about 15 kilotons. Modern nuclear weapons have yields hundreds of times higher than that. …

The IAEA said Iran is poised to double its output of higher-enriched uranium at its fortified underground facility – a development that could put Tehran within months of being able to make the core of a nuclear warhead.

And this information from Reza Khalili (“a pseudonym for a former CIA operative in Iran’s Revolutionary Guards”) at Radical Islam is even worse:

Just as the latest International Atomic Energy Agency report increased alarm about Iran’s illicit nuclear program, now comes word that the Islamic regime has created even more secret nuclear sites.

The IAEA report indicated that not only has Iran completed installation of 2,784 centrifuges at Fordow, the previous secret site deep in a mountain believed to be immune to air strikes, but also could within days increase output of highly enriched uranium to the 20-percent level, well on the way to nuclear weapons.

Iran has started to feed uranium hexafluoride gas into four new cascades, increasing the number of centrifuges at Fordow from 700 to 1,400, therefore doubling its output of highly enriched uranium and cutting the time needed for having enough high-enriched material for one nuclear bomb. The regime already has enough low-enriched uranium for six nuclear bombs if further enriched. …

Peter Vincent Pry, formerly with the CIA and now executive director of the Task Force on National and Homeland Security, a congressional advisory board, regards the discovery of another Iranian underground nuclear site as ominous.

“Reliable sources in recent months appear to have disclosed two more previously unknown facilities serving Iran’s nuclear program,” Pry said. “Moreover, the sources have provided some credible evidence that at least one of these facilities is actively engaged in nuclear weaponization. If any of these allegations is even partially true, the whole timeline for Iran developing a nuclear weapon must be recalculated. The advent of a nuclear-armed Iran is much nearer than assumed by the Obama administration.”

Pry warned that the United States cannot afford to let Iran, the leading sponsor of international terrorism, develop even a single nuclear weapon.

The IAEA reported that Iran removed fuel rods from the Bushehr light water reactor … on October 22. …

Although light water reactors are not designed to produce weapons-grade plutonium, the design can produce large amounts of weapons-grade plutonium in a short period of time. In a matter of months … the low-enriched uranium fuel in the Bushehr reactor could yield enough plutonium for dozens of atomic bombs …

It would take only three or four months to convert the plutonium from the Bushehr reactor’s spent fuel rods into weapons-grade plutonium .. Depending on how long the fuel rods were used before Iran removed them on Oct. 22, they would yield between 150 kg and 300 kg of plutonium, or enough fissile material for 25 to 50 bombs.

The Hiroshima bomb devastated an area of about 1000 sq km. Israel including East Jerusalem and the Golan Heights measures 22,072 sq km; with Judea and Samaria (the “West Bank”), 27,793 sq.km.

So if an Iranian bomb 3 times the power of the Hiroshima bomb were dropped on Israel, it could devastate 3000 sq km. Twenty-five such bombs could lay waste the whole of Israel and a large area adjacent to it.

The intention of the Iranian leaders is to destroy Israel. There is no sign that any effective steps are being taken to stop Iran from doing so with nuclear bombs.
